RELATED APPLICATION

The present application claims the benefit of U.S. Provisional Application No. 62/300,410 filed Feb. 26, 2016, which is hereby incorporated herein in its entirety by reference.

TECHNICAL FIELD

Embodiments relate generally to computer systems for controlling local system resources. More particularly, embodiments relate to systems and methods for controlling local system resources through a web browser.

BACKGROUND

Most computer systems allow peripheral devices, such as Universal Serial Bus (USB) devices, to be plugged in or otherwise connected to the computer system. USB devices can include audio, printer, mass storage, video, imaging, security devices, medical devices, and so on. Currently, no web browser-agnostic solution exists for controlling, communicating with, or interacting with these devices. Traditional control applications for peripheral devices typically include a GUI to control the device. However, this type of solution is incompatible with web browser-based solutions. A web browser-agnostic solution is desirable because of the ubiquity of web browsers and the consistent look and feel of browser-based user interaction.

However, web browsers typically execute on a user machine under strict security. This strict security is for obvious reasons, as users can interact with any number of malevolent actors or malicious content through the Internet. As a result, access to local system resources such as connected USB devices is typically restricted.

In addition, it is difficult for web servers to determine which web browser and which device manager are on the same computer due to web browser security wrappers. Techniques to determine common computing environments exist (such as by utilizing fingerprinting libraries), but are often inaccurate. For example, fingerprints from a web browser and another local application executing on the same computer have been incorrectly identified as executing on different computers with existing fingerprinting solutions.

Further, new web browsers are more focused on security than previous versions. As a result, many web browsers are restricted from accessing local computer resources, such as coupled peripheral devices. However, web browsers are now ubiquitous on computing devices. Further, in many environments, such as hospitals, only certain (restrictive and peripheral device-disabled) web browsers are allowed, thus requiring solutions for accessing local computer resources from any web browser.

Therefore, there is a need for systems and methods for controlling, communicating with, and interacting with local system resources through a web browser.

SUMMARY

In one embodiment, a system for initializing control of a peripheral device comprises a peripheral device configured to be operably coupled to a user computing device; and a user computing device operably coupled to a communications network, the user computing device comprising: a web browser configured to present web pages to a user, and a device manager configured to operate the peripheral device and request a login page from the web server viewable on the web browser upon coupling of the peripheral device with the user computing device, the device manager including a device manager web server configured to receive a communication from the web browser; wherein the web browser is further configured to receive an authentication token from the web server after transmission of user login information to the web server entered through the login page and pass the authentication token to the device manager through the device manager web server, and wherein the device manager is further configured to authenticate the device manager with the web server by transmitting the authentication token to the web server.

In one embodiment, a method for initializing control of a peripheral device comprises installing a device manager on a user computing device, the device manager configured to operate the peripheral device and including a device manager web server; receiving, with a web server, login information from a web browser executing on the user computing device; transmitting, from the web server, an authentication token to the web browser; receiving, with the web server, the authentication token from the device manager; and pairing the web browser and the device manager based on the shared authentication token so that peripheral device commands can be transmitted by the web server to the device manager.

In one embodiment, a method for controlling a peripheral device with a web browser, the web browser paired to a particular device manager comprises receiving, with a web server, a peripheral device command from a web browser executing on a user computing device; identifying the particular device manager paired with the web browser; routing the peripheral device command to the particular device manager identified as paired with the web browser; and executing the peripheral device command on the peripheral device using the device manager.

In various embodiments, systems allow any web browser running on a user computer to communicate with a device plugged into the user computer. In this way, systems provide web browser-agnostic solutions for peripheral device communication.

In another aspect, a headless device manager installed on the user computer serves as a communication mechanism between a USB device such as an infusion pump and a web browser on the user computer. In embodiments, the headless device manager comprises an engine configured to operate on the user computer without a graphical user interface. Accordingly, the the headless device manager receives inputs and provides output through other interfaces, such as the operably coupled web browser.

In another aspect, users are provided a familiar browser-based experience to interact with the device. The device and web browser communication with an external server can be hidden from the user.

In another aspect, the connected device can be a medical device such as an infusion pump. Embodiments of systems and methods decouple the user computer-web server communication from the proprietary device-device manager communication so control via a web browser can be conducted for any device.

In another aspect, systems allow for modular operation. For example, health care providers can push remote uploads from the connected user device using the provided interfaces from the web server to the device manager and to the device. In such embodiments, other operation of the device is not impacted or affected.

In another aspect, a network provider can provide a web server and access to web server content to control a peripheral device through a device manager application installed on a user computer. In embodiments, the network provider can provide a server engine and database content as described herein. For example, the network provider can provide a server engine including predetermined access commands for the peripheral device and web content that can be transmitted to a web browser operated by a user. In an embodiment, the network provider can further provide access to a downloadable device manager application for installation on a user computer configured to interface to a user peripheral device.

In another aspect, an end user can operate a peripheral device using a user computer and the hardware and software tools described herein; particularly a web browser. For example, an end user can install a device manager application having a device manager web server configured to listen for local calls from the web browser executing on the user computer. The end user can operate the peripheral device with the web browser. In particular, the end user can interface with the web browser user interface to transmit peripheral device commands to a web server, which can relay the calls to the device manager application.

The above summary is not intended to describe each illustrated embodiment or every implementation of the subject matter hereof. The figures and the detailed description that follow more particularly exemplify various embodiments.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to FIG. 1, a block diagram of a system for controlling a peripheral device with a web browser is depicted, according to an embodiment. System 100 generally comprises a peripheral device 102, a user computer 104, and a web server 106.

Embodiments of system 100, and the corresponding methods of configuring and operating system 100, can be performed in cloud computing, client-server, or other networked environment, or any combination thereof. The components of the system can be located in a singular “cloud” or network, or spread among many clouds or networks. End-user knowledge of the physical location and configuration of components of the system is not required.

As will be described, the system and/or its components or subsystems can include computing devices, microprocessors, modules and other computer or computing devices, which can be any programmable device that accepts digital data as input, is configured to process the input according to instructions or algorithms, and provides results as outputs. In an embodiment, computing and other such devices discussed herein can be, comprise, contain or be coupled to a central processing unit (CPU) configured to carry out the instructions of a computer program. Computing and other such devices discussed herein are therefore configured to perform basic arithmetical, logical, and input/output operations.

Computing and other devices discussed herein can include memory. Memory can comprise volatile or non-volatile memory as required by the coupled computing device or processor to not only provide space to execute the instructions or algorithms, but to provide the space to store the instructions themselves. In embodiments, volatile memory can include random access memory (RAM), dynamic random access memory (DRAM), or static random access memory (SRAM), for example. In embodiments, non-volatile memory can include read-only memory, flash memory, ferroelectric RAM, hard disk, floppy disk, magnetic tape, or optical disc storage, for example. The foregoing lists in no way limit the type of memory that can be used, as these embodiments are given only by way of example and are not intended to limit the scope of the invention.

In embodiments, the system or components thereof can comprise or include various modules or engines, each of which is constructed, programmed, configured, or otherwise adapted, to autonomously carry out a function or set of functions. The term “engine” as used herein is defined as a real-world device, component, or arrangement of components implemented using hardware, such as by an application specific integrated circuit (ASIC) or field-programmable gate array (FPGA), for example, or as a combination of hardware and software, such as by a microprocessor system and a set of program instructions that adapt the engine to implement the particular functionality, which (while being executed) transform the microprocessor system into a special-purpose device. An engine can also be implemented as a combination of the two, with certain functions facilitated by hardware alone, and other functions facilitated by a combination of hardware and software. In certain implementations, at least a portion, and in some cases, all, of an engine can be executed on the processor(s) of one or more computing platforms that are made up of hardware (e.g., one or more processors, data storage devices such as memory or drive storage, input/output facilities such as network interface devices, video devices, keyboard, mouse or touchscreen devices, etc.) that execute an operating system, system programs, and application programs, while also implementing the engine using multitasking, multithreading, distributed (e.g., cluster, peer-peer, cloud, etc.) processing where appropriate, or other such techniques. Accordingly, each engine can be realized in a variety of physically realizable configurations, and should generally not be limited to any particular implementation exemplified herein, unless such limitations are expressly called out. In addition, an engine can itself be composed of more than one sub-engines, each of which can be regarded as an engine in its own right. Moreover, in the embodiments described herein, each of the various engines corresponds to a defined autonomous functionality; however, it should be understood that in other contemplated embodiments, each functionality can be distributed to more than one engine. Likewise, in other contemplated embodiments, multiple defined functionalities may be implemented by a single engine that performs those multiple functions, possibly alongside other functions, or distributed differently among a set of engines than specifically illustrated in the examples herein.

Peripheral device 102 generally comprises a mobile device, such as a USB device. In an embodiment, peripheral device 102 comprises any device that utilizes USB connections to connect to a computer. In various embodiments, peripheral device 102 can include an audio, printer, mass storage, video, imaging, security, or medical device. In an embodiment, peripheral device 102 can store system 100 data. In embodiments, as will be described, peripheral device 102 can be configured or controlled by user computer 104. For example, peripheral device 102 can comprise a medical pump that can be configured for operation with a user. In an embodiment, peripheral device 102 lacks any processing capability on its own. In such embodiments, peripheral device 102 can be operated on by processors of user computer 104, for example.

As depicted in FIG. 1, peripheral device 102 is operably coupled to user computer 104. In embodiments, peripheral device 102 is physically connected to user computer 104, such as by a cable. In an embodiment, peripheral device 102 can be connected to user computer 104 by a USB cable and exchange data over a USB protocol. In other embodiments, other wired hardware and suitable wired protocols such as FIREWIRE, PS/2, EEPROM, or ETHERNET can be utilized. In other embodiments, peripheral device 102 is operably coupled to user computer 104 by a wireless interface. For example, peripheral device 102 can comprise wireless hardware such as NFC hardware, RFID hardware, WIFI hardware, BLUETOOTH hardware, or any other suitable data transmission hardware and related circuitry, firmware, software, drivers, and other components.

User computer 104 generally comprises a device manager 108 and a web browser 110. In embodiments, as depicted in FIG. 1, user computer 104 is operably coupled to peripheral device 102 and web server 106.

Device manager 108 is configured to manage the interface to peripheral device 102. As such, device manager 108 is configured with hardware and firmware to communicate using the same protocol implemented by peripheral device 102. Device manager 108 can utilize a file system to control how data is stored and retrieved on peripheral device 102. In an embodiment, device manager 108 can implement a proprietary protocol for communication with peripheral device 102.

In embodiments, device manager 108 further comprises device manager (DM) web server 112. In an embodiment, device manager 108 utilizes DM web server 112 for communication with external components of system 100 via web browser 110, as will be described. In an embodiment, DM web server 112 comprises a small web server executing on user computer 104 that can only be called from the local user computer 104 (and particularly, local web browser 110). DM web server 112 is configured to listen for the local call from web browser 110. As depicted in FIG. 1, DM web server 112 is contained exclusively within device manager 108 such that access to DM web server 112 is limited further only to components of user computer 104 that can interface to device manager 108. In embodiments, DM web server 112 provides an application program interface (API) for access to its communications capabilities. Accordingly, access can be limited to those programs (such as web browser 110) that are uniquely identified to have the proper identification within user computer 104. In other embodiments, access to DM web server 112 is provided by hardware identifiers, such as by certain communication ports.

Device manager 108 can be implemented in any appropriate application for rendering web pages in web browsers, such as, e.g., NW.js (formerly known as Node Webkit). In embodiments, NW.js provides a lightweight infrastructure that can implement both a client application and a web server in a single package. In other embodiments, device manager 108 can be implemented in C#, Java, or any other suitable programming language to execute on the hardware of user computer 104. Device manager 108 can utilize JSON (JavaScript Object Notation) lightweight data-interchange format for message transport. In still other embodiments, a lightweight HTTP server and port listener can be implemented as DM web server 112. In embodiments, device manager 108 has no user interface.

In other embodiments, device manager 108 can utilize a web service that makes itself available over the coupled network, using for example, a standardized XML messaging system. Device manager 108 can further communicate with other components on system 100 using a network socket architecture. For example, device manager 108 can communicate directly with web server 106. This communication path between device manager 108 and web server 106 can therefore be assigned a socket identifier. In other embodiments, an address and a port ID can further be assigned by web server 106.

In embodiments, device manager 108 is further configured to transmit and receive tokens utilized by components of system 100 for token-based authentication. For example, JSON Web Tokens (JWT) are a compact and self-contained way for securely transmitting information between parties as a JSON object. In an embodiment, JWT tokens can include iss (issuer), exp (expiration time), sub (subject), and (audience), and other fields that can be utilized within system 100. For example, a user ID (issuer) can be passed from device manager 108 to web server 106 as a supplemental lookup field, as will be described.

Web browser 110 generally comprises a software engine executable on user computer for retrieving, presenting and traversing information resources on a network. An information resource accessible by web browser 110 can be identified by a Uniform Resource Identifier (URI/URL) that may be a web page, image, video or other piece of content. Hyperlinks in information resources enable users easily to navigate web browser 110 to related resources. Web browser 110 is primarily intended to use the World Wide Web, but can also be used to access information provided by web servers in private networks or files in file systems, as described herein. Web browser 110 can be implemented in Ember, ASP, HTML, JavaScript, or any other suitable programming language to execute on the hardware of user computer 104. Example web browsers 110 include FIREFOX, GOOGLE CHROME, INTERNET EXPLORER, OPERA, SAFARI, and MICROSOFT EDGE.

Web server 106 generally comprises a server engine 114 and a content database 116. Web server 106 can be implemented using Node JS and the accompanying website provided by server engine 114 can be implemented by Angular JS. In other embodiments, web server 106 can be implemented in Internet Information Services (IIS), Apache, or any other suitable host service.

Server engine 114 is configured to provide information resource content to web browser 110 and to communicate directly with device manager 108 in certain embodiments. Accordingly, socket IDs can be assigned to both the communication instance between server engine 114 and web browser 110 and the communication instance between server engine 114 and device manager 108. Socket identification data can be stored along with web browser-device manager pairs, as will be described. In further embodiments, sockets can be utilized to push updates for display by web browser 110 (for example, activity of the connected peripheral device), rather than the traditional operation of web browsers that require a user request before updating.

With respect to server engine 114 communications with web browser 110, server engine 114 can provide a web page, image, video, file system directory, or other user interface to peripheral device 102 via web browser 110. In an embodiment, server engine 114 is configured to process and deliver web pages to web browser 110. The communication between web browser 110 and server engine 114 can be by Hypertext Transfer Protocol (HTTP). Pages delivered by server engine 114 can include HTML documents, which can include images, style sheets and scripts in addition to text content.

In an embodiment, server engine 114 can provide a browser user interface (BUI) for interacting with peripheral device 102 via controls presented within web browser 110. For example, server engine 114 can provide a website-style interface to the file structure and server of peripheral device 102. In other embodiments, server engine 114 can provide a layer abstracted from the file structure of peripheral device 102 such that certain predefined actions can be executed with peripheral device 102. For example, if peripheral device 102 is a medical device, server engine 114 can provide a hyperlink viewable with web browser 110 to load a particular medical device application or drug library. In another example, server engine 114 can provide a hyperlink viewable with web browser 110 to update the firmware of peripheral device 102.

In embodiments, server engine 114 can execute processes hidden from the user. For example, server engine 114 can communicate directly with device manager 108. In an embodiment, device manager 108 can transmit information directly to server engine 114. Likewise, once initial handshaking or authentication is established via communication with web browser 110, server engine 114 can transmit information directly to device manager 108 without going through web browser 110.

Content database 116 can store the resources utilized by server engine 114. In embodiments, content database 116 can comprise local volatile or non-volatile memory. In another embodiment, content database 116 can be a general purpose database management storage system (DBMS) or relational DBMS as implemented by, for example, ORACLE, IBM DB2, MICROSOFT SQL SERVER, PostgreSQL, MYSQL, SQLITE, LINUX, or UNIX solutions, in embodiments. For example, content database 116 can store web page templates or designs. In other embodiments, content database 116 can store substantive device content, such as peripheral device 102 drivers or executables.

In an embodiment, browser-based control can be executed locally without web server 106. In such embodiments, only local data stored on, for example user computer 104, would be utilized for display on web browser 110. For example, web browser 110 can utilize DM web server 112 which can comprise an engine similar to server engine 114 and content similar to content database 116. DM web server 112 can accordingly populate web pages with URL calls similar to those executed by web browser 110, but such calls would remain local to user computer 104. Accordingly, web pages could be derived using the token string query described above.

Referring to FIG. 2, a block diagram of another system 200 for controlling a peripheral device with a web browser is depicted, according to an embodiment. System 200 generally comprises a peripheral device (not shown), and user computer 104 from FIG. 1. System 200 further comprises a cloud-based web server 206 implemented in a cloud architecture.

Cloud-based web server 206 comprises a cloud-based server engine 214 and a plurality of content databases 216. Cloud-based server engine 214 can be distributed across multiple computers or computing hardware connected over a network. In an embodiment, the functionality of cloud-based server engine 214 can be substantially similar to server engine 114 in FIG. 1. Likewise, content databases 216 can be distributed across multiple storage devices or storage hardware connected over the network. In an embodiment, the functionality of content databases 216 can be substantially similar to content database 116 in FIG. 1.

User computer 104 is depicted as interfacing with cloud-based server engine 214. Accordingly, user computer 104 can know the identity of just one of the distributed computers making up cloud-based server engine 214, or it can know more than one of the distributed computers making up cloud-based server engine 214. Cloud-based server engine 214 can thus provide information resource content to user computer 104 and to communicate directly with user computer 104 via any of the distributed computers using content from any of the distributed content databases 216.

Referring to FIG. 3, a block diagram with annotated workflow of a system 300 for controlling a peripheral device with a web browser is depicted, according to an embodiment. System 300 generally comprises a device 300, a user PC 304, and a server 306.

Device 300 generally comprises a mobile device that is capable of being plugged in and communicatively coupled to user PC 304. In an embodiment, device 300 is substantially similar to peripheral device 102 as described in FIG. 1.

User PC 304 generally comprises a computing device operable by a user that can receive communication coupling from device 302. In an embodiment, user PC 304 is substantially similar to user computer 104 as described in FIG. 1. User PC generally comprises a device manager 308 and a web browser 310.

Device manager 308 is configured to manage the interface to device 302. In an embodiment, device manager 308 can comprise system functions. Accordingly, an icon for device manager 308 can be located in the System Tray for easy access to device manager 308 functions.

Web browser 310 generally comprises a software engine executable on user PC 304 for retrieving, presenting and traversing information resources on a network coupling system 300. In an embodiment, web browser 310 is substantially similar to web browser 110 as described in FIG. 1.

Server 306 is configured to provide information resource content to web browser 310 and to communicate directly with device manager 308, in certain embodiments. In an embodiment, server 306 is substantially similar to web server 106 or cloud-based web server 206 as described in FIG. 1.

An annotated workflow of an example initiation operation is also depicted in FIG. 3 with reference to elements 351-356.

At 351, device 302 can be plugged in to user PC 304. For example, a USB connector cable can be communicatively coupled on one end to device 302 and on another end to user PC 304. Once coupled, device 302 and user PC 304 can initiate handshaking or other initialization procedures to establish a communication channel. The communication channel can allow such that data and/or commands to be transmitted and/or received at either end (both device 302 and user PC 304). For example, device 302 can be registered with device manager 308. In other embodiments, device 302 can be communicatively coupled via wireless protocol. In such embodiments, a physical cable is not needed; instead, connection is made via wireless handshaking.

At 352, device manager 308 can open a login page web site populated from server 306 using web browser 310. For example, device manager 308 can request a login page from server 306. In response to that request, server 306 can configure the login web page viewable to the user on web browser 310.

At 353, the user can access the graphical user interface components of web browser 310 to log in. For example, the user can enter username and password, or other identifying information in combination with shared secret password information into one or more web page fields. This information is sent to server 306 and verified to be accurate from data in server 306 databases. In an embodiment, server 306 can send back an authentication token to web browser 310.

At 354, web browser 310 calls device manager 308 via the local system IP address, which is ubiquitous across all computers, and passes the authentication token in the query string. For example, web browser 310 can use the query string http://127.0.0.1:8000?authtoken=abc123. In embodiments, the authentication token can be passed in cleartext within the string, or be hashed or otherwise encrypted for additional security within user PC 304. In other embodiments, web browser 310 can call device manager 308 via function call or other common user PC bus access. In embodiments, a pointer or database identifier to the authentication token can be passed to device manager 308 instead of in a query string.

At 355, device manager 308 sends the authentication token to server 306 using, for example, its socket connection or other web service-based connection. Server 306 can then establish which particular device manager 308 and web browser 310 are on the same user PC 304 because of the shared authentication token. This linked set data for device manager 308 and web browser 310 can be stored on server 306.

In an embodiment, a database stores pairs of web browsers-device managers including the socket ID for each connection of the web browser to the web server and the device manager to the web server. Socket IDs are in a one-to-one cardinality. In another embodiment, a user ID (issuer) in a JWT token can be passed from device manager 308 to server 306 as a supplemental lookup field to be stored with the pairs.

Once the particular device manager 308 and web browser 310 set is established, device 302 can then be controlled by server 306. For example, at 356, a user can enter commands related to device 302 in web browser 310. Web browser 310 can send the user commands to server 306. Server 306 can relay those commands to device manager 308 for operation of device 302. In an example, a user can command device 302 to be erased in web browser 310. The erase command is forwarded to server 306 and then to device manager 308, which commands the erase of device 302. In another example, if a command is transmitted to server 306 via web browser 310, a lookup of the corresponding device manager socket ID can be conducted due to the socket ID storage in the coupled storage database of server 306.

Referring to FIG. 4, a flowchart of a method 400 for initiating for control of a peripheral device with a web browser is depicted, according to an embodiment. Method 400 can be implemented by, for example, systems 100, 200, or 300 as described above. However, particular reference will be made to system 100 while describing method 400 for ease of explanation.

At 402, a device manager is installed on a user device. In embodiments, a one-time install of device manager application 108 is conducted on user computer 104. For example, device manager 108 can be installed from a network resource or other resource coupled to user computer 104. Device manager 108 is configured to automatically execute in the system tray when the computer is started. In embodiments, device manager 108 has no user interface.

At 404, a user can connect a peripheral device to the user computer. In embodiments, the user physically connects peripheral device 102 and user computer 104 via USB connection. In embodiments, once connected, device manager 108 can initialize or otherwise prepare peripheral device 102 for operation with user computer 104.

At 406, the device manager connects to a web server and opens a login interface. In embodiments, device manager 108 utilizes web browser 110 to request login content from web server 114. In particular, server engine 114 can receive a login content population request and subsequently access content database 116 to populate login content (such as GUI login fields) for display on web browser 110. In one embodiment, the request for login content is not known to the user operating user computer 104 until web browser 110 is populated with login fields. In such embodiments, web browser 110 can be automatically executed in response to the request. In other embodiments, the user initiates the request for login content by accessing web browser 110 and commanding a particular access request, which can be populated by default on web browser 110. In still other embodiments, a combination of user connecting peripheral device 102 and accepting a prompt initiates the request for login content.

At 408, the user logs in via the login interface using a web browser. The web server verifies the login information and returns an authentication token to the web browser. In embodiments, the user can interact with user interface fields in web browser 110 to input login information. Web browser 110 can transmit this data to server engine 114. In an embodiment, the login information can be verified as accurate from data stored in content database 116. Once verified, server engine 114 transmits an authentication token to web browser 110. In an embodiment, the authentication token can be generated by server engine 114.

At 410, the web browser passes the authentication token to the device manager. In embodiments, web browser 110 passes the authentication token to device manager 108. In one embodiment, web browser 110 can physically pass the authentication token data to device manager 108. In other embodiments, web browser 110 can pass a pointer or query holding the data to device manager 108.

At 412, the device manager passes the authentication token to the web server. In embodiments, device manager 108 utilizes JSON or a suitable web service to transmit the authentication token. For example, device manager 108 can prepare a network packet, such as an HTTP, FTP, or other communications protocol packet including the authentication token using a JSON API. Server engine 114 receives the authentication token and links device manager 108 and web browser 110. In an embodiment, the device manager 108 and web browser 110 pair data can be stored in content database 116.

Referring to FIG. 5, a flowchart of a method 500 for controlling a peripheral device with a web browser is depicted, according to an embodiment. Method 500 can be implemented by, for example, systems 100, 200, or 300 as described above. However, particular reference will be made to system 100 while describing method 400 for ease of explanation. Method 500 can be executed after execution of methods for initiating control of a peripheral device with a web browser, such as method 400.

At 502, a user inputs a web server command via a web browser. In embodiments, user can access web browser 110 to input a command related to peripheral device 102. For example, the web browser 110 can display an interface of user-selectable commands related to peripheral device 102, such as predefined peripheral device functions represented as hyperlinks. In other embodiments, web browser 110 can include buttons, text fields, or other web page content corresponding to commands that a user can interact with to provide a device command. In embodiments, the web server can populate the fields displayed by web browser 110. Predefined control commands can be populated, in embodiments.

At 504, the web server receives the user-inputted command. In embodiments, web browser 110 utilizes its communication firmware in combination with communication hardware of user computer 104 to transmit the user-inputted command to server engine 114 over the network coupling the components of system 100. For example, web browser 110 can convert the user-inputted peripheral device command into a network packet structure. In an embodiment, the network packet can comprise an IP packet having a header and a payload.

At 506, the web server routes the command to a device manager. In embodiments, server engine 114 transmits the command to device manager 108. For example, server engine 114 can transmit a network packet including the device command over the network coupling the components of system 100. In an embodiment, server engine 114 can access a database, such as content database 116 to determine the particular device manager corresponding to the web browser that transmitted the user-inputted command. For example, a web browser-device manager pair can be stored in content database 116. The pair data can further store the particular user computing device, such as user computer 104 that corresponds to the web browser-device manager pair. In such embodiments, prior to routing the command, the web server can search the database for the web browser-device manager pair data to determine the proper target device manager. For example, the database can be searched based on a web browser identifier to find the corresponding device manager in the pair. In an embodiment, a web browser identifier can comprise a unique ID for the web browser, such as a network address, software identifier (process ID, etc.), hardware identifier (MAC address, etc.), socket ID, or any combination thereof.

At 508, the device manager executes the command on the peripheral device. In embodiments, device manager 108 commands peripheral device 102 with the substantive command. For example, device manager 108 can utilize the particular driver it has stored for peripheral device 102 to execute the command.

Control of a peripheral device can be initiated not only by the user (as depicted in FIGS. 4-5, but by the device itself, or by a server. For example, referring to FIG. 6, a flowchart of a method 600 for controlling a peripheral device initiated by the peripheral device is depicted, according to an embodiment. Method 600 can be implemented by, for example, systems 100, 200, or 300 as described above. However, particular reference will be made to system 100 while describing method 600 for ease of explanation. Method 600 can be executed after execution of methods for initiating control of a peripheral device with a web browser, such as method 400.

At 602, a user can connect a peripheral device to the user computer. In embodiments, the user physically connects peripheral device 102 and user computer 104 via USB connection. In embodiments, once connected, device manager 108 can initialize or otherwise prepare peripheral device 102 for operation with user computer 104.

At 604, a device manager coupled to the peripheral device transmits a command related to the peripheral device to a web server. For example, device manager 108 can package the command related to peripheral device 102 and transmit it to web server 106 for receipt by server engine 114. In an embodiment, command can be “monitor the connected device during upload.” This command can be issued to web server 106 without user input.

At 606, the web server routes the command to the web browser. For example, web server 106 can route the device command to web browser 110. In the “monitor” example above, web server 106 can further transmit display interface data or packaging related to the device monitoring that web browser 110 can display. For example, an “Uploading . . . ” interface can be provided that is unique to that command.

At 608, web browser 110 displays the device data and the display interface data sent by the web server, if applicable. For example, web browser 110 can generate a new web page having an uploading icon and a progress bar reflecting the status of the upload.

In an embodiment, method 600 can execute 604-608 iteratively for a single command. For example, considering the example “monitor the connected device during upload” command, web browser 110 can change display at important steps during the upload corresponding to the sub-commands that make up the larger “monitor the connected device during upload” command. An initial sub-command comprises a start of the uploading. Accordingly, at the start of uploading, device manager 108 can route a “start of the uploading” sub-command to web browser 110 via web server 106 indicating that peripheral device 102 has successfully started uploading. A second sub-command comprises “load into device” in which data is transitionally stored in the peripheral device. Accordingly, device manager 108 can route a “data loaded into device” sub-command to web browser 110 via web server 106 indicating that peripheral device 102 has successfully loaded the requisite data. Finally, a third sub-command comprises “upload to storage server” in which the data temporarily stored in peripheral device can be transmitted to the storage server. Accordingly, device manager 108 can route an “upload complete” sub-command to web browser 110 via web server 106 indicating that peripheral device 102 has successfully transmitted the data to the storage server.

In another embodiment, a server coupled to the network, such as web server 106, can poll device manager 108 for updates to the peripheral device. Similar to method 600, once the peripheral device is connected, web server 106 can poll device manager 108 for updates from peripheral device 102 to then send for display to web browser 110. In an embodiment, the web page displayed by web browser 110 can be static except for the dynamically-updated socket connection pushing new data to a particular web browser 110 field. For example, if peripheral device 102 is disconnected, device manager 108 can be polled via web server 106 for display on web browser 110.
